LS-DYNA and modeFRONTIER for Material Model Calibration at Automobili Lamborghini
CHALLENGE - CFRP composites have been used in Automobili Lamborghini since 1983. Today, the main challenge is to reproduce their structural behavior by developing suitable numerical models whose set-up requires just simple experimental tests. Automobili Lamborghini and EnginSoft collaborated to perfect sophisticated manufacturing applications and FE technical support with the aim to provide such numerical models.
SOLUTION - While the engineers relied on modeFRONTIER's capabilities, the procedure has been to calibrate the constitutive parameters of LS-DYNA's advanced material models, and to use them for prediction, design optimization and robustness analysis. In particular, two different composite materials, “RTM 1400” and “PREPREG 977- 6”, have been investigated with the objective to exploit the calibrated material models in impact situations of automotive structural components.
BENEFITS - In this way, the amount of expensive experimental tests could be reduced. This approach also allows better understanding of the influence of physical and geometrical variables on the composite dynamic structural response or, respectively, to obtain improved solutions for industrial case studies.
